 a lost game


Here are some comments I have for the game:

14 f5 : I think this position should be better for white. The database gives this as a .44 advantage.
After this I need to find some way to rearrange my pieces to kick the knights. I think moving to f6 seems like a good idea since opening the f-file is likely to be fine for black. The problem is that if I retreat my bishop, the c4 pawn falls. Probably what I was doing was ok but I should have not played h4 as that loses the exchange, and recapturing with the bishop may in fact be stronger as it gives white more piece play. In fact black could have blocked the position with h4. Instead he played hxg5 which I think gives white some attacking chances there.
30: hxg5. This I think is a mistake. Now white has a plan to bring the queen to h6 and give mate on g7. However, I could not immediately play qf4 because of Bxd4 Qh4 Bxf6 gxf6 Qxa2+ ne2 qb2 which eyes the f6 pawn and stops qh6. I chose nge2 because it tries to plug up the a7 g1 diagonal by protecting the knight. It also has the purpose of preventing a check on a2 later. after that I expected Bxd4 Nxd4 and either Rc8 or Qc5. I thought I had calculated that rc8 immediately doesn't work, but I overlooked the rc5 move, and chose the one way of routing the queen that doesn't protect g5. After moving the queen back to d2 to protect g5, it is too late and black has a winning attack.
31 .. Rc8. After this move I know that even if I play Qe1 or Qf4 black can route the queen to f8 via c7 and d8 so he is fine, but having that queen tied down gives white some chances.

Throughout the game I cannot see the sense in pushing your kingside pawns.

After you play f6 there is only one way to attack and that is via the h-file which cannot be achieved, so black's king is quite save. On the other hand your own king is very weak. This is typical for hedgehog positions, black has no real weakness and waits for white to overextend.

I don't know why black took the exchange, because after 19... d5 you are at first glance completely lost (engine says -2), but 19...Nxd3 20Qxd3 d5 is also good for black. After 19... d5 20...Nxd3 21Qxd3 Qg3+ is threatened. The engine wants to give a piece on d5 for 2 pawns, but white is much worse as Ng3 is still a threat...

Where was this played? Was this a correspondence game? I think black was using a computer...waaaaaaaaaaaaaay to many first choice Houdini moves. Moves 11-39 are 95% 1st or 2nd choice Houdini moves.

I think it's difficult to prove the use of engines in correspondence chess, by the way are engine allowed?

Zibbit says that the moves are the ones that Houdini suggests, however, some of them are logical moves which are not hard to find.
Also, I think that my comment that 19...d5 is winning and stronger than Ng3, should be found by an engine, especially in long-term analysis.

The second game is a little uninspired, nothing really happens. Only the rook endgame was not played well by both sides.

 Re: a lost game
As an addition to my last post:
Few days ago I played blitz game as guest on FICS and after analysing my opponent told me that my moves were 90% inline with Chessmaster.
In online chess it's always difficult to prove cheating. Sometimes, you are quite sure, like in a Blitz game of mine, where my opponent played the whole 52 moves in ~80 seconds. I think even Zibbit can't do that and he's really fast. But you can never be 100% sure.
