T75 Highlights: Round 2

Ajolote wins a wild one - lots of great tactics and a key sacrifice. 
This is the sort of game I love. White's King was engineered into an inescapable position after setting up a mating net and a sacrifice.

T74 Playoffs: Round 3


Insan996 wins first game in final Championship round! Wild Caro-Kann variation ruled!

GOTW winner! Here is write up from Megasus!

Another Caro-Kann defense ; site says this is a (fantasy) Tartakower, but it really goes down a totally different path. ChessTempo has this as the Maroczy var, denoted by 3. p-f3.. and not the Maroczy Gambit, since dxe4 is declined until move 17 !.. Even odds on either winning or a draw, until move 5 ; B-d3 puts it at 66% draw chances, with no winning chances for W..The line narrows to one response, at move 6 ; Black goes out of system first as his response to B-f4 should have been p-f6. N-d7, and we're OOB... p-e5 for Black ; then W Should have taken the N on h6. But he stopped to pressure Q first, with B-g5. That pushed Q-b6, which was forcing W to protect b2 in some way. W didn't, thinking he would be able to grab the h8 R after BxN BxB QxB, on h6. Making it ok to lose his a1 R. But R-f8 for Black, saves his, and now W's Qside is  compromised.... The Game is basically lost from here, as the extra R for Black plus his white B, 2nd N and Q begin to take  their toll on Qside and the middle. White Q is pushed off to h column, to avoid a Q trade, so it is mostly out of the mix in the middle. Black is able to open up e column next, and W has little defense after the fR comes over to e8 to control it. W has  attacking moves, but nothing of consequence that can slow Black's roll enough. Black wins all the trades inhte middle,  overwhelming it. A 2nd decline by W of a Q Trade, leads to the White K getting separated from his pieces left, and the  mating sequence...
