Test Position

Post by Robert Flesher »

Fat Fritz plays Qc3? and loses, yet Leela and others avoid it with ease. Why is Fat Fritz so blind here?



Analysis by Fat Fritz (in lc0) rtx:

1...Qc3 2.a6 Qc6+ 3.Qxc6 Rxc6 4.a7 Rc7 5.Rexc2 Rxa7 6.Rc7 Rxc7 7.Rxc7 Rd8 8.g4 h6 9.Rc2 Rd1 10.f3 Rd8
The position is equal: = (50% +7% =86% -7%) Depth: 11/35 00:00:31 525kN

After Qc3 best line is 2. Rcxc2 Qxc2 3. Rxc2 Rxc2 4. a6 Rcc8 5. a7 Ra8 BUT

[d]r4rk1/P4ppp/8/1Q6/8/6PP/5PK1/8 w - - 0 6
This is not winnable I guess.
