Subject: TB's & Castling

Hyatt said in an earlier post that TB's don't take into account the ability to
castle because it would be a waste.

However, when I feed this position into any engine, it solves it in 0.00 as a TB
win.

[D]5Q1Q/5Q1Q/5Q1Q/5Q1Q/8/6P1/6k1/4KR1R w K -

It shows 20 possible moves, all from TB's I am guessing.

I cannot cut and paste the eval, because there isn't one, but I have:

1.+ - (#4) Rf4
2.+ - (#4) Kd1
3.+ - (#4) Kd2
4.+ - (#4) Ke2
5.+ - (#4) Rf5
6.+ - (#4) Rf6
7.+ - (#4) Rf7
8.+ - (#4) Rf8
9.+ - (#4) Rhg1+
10.+ - (#4) Rh4
11.+ - (#4) Rh5
12.+ - (#4) Rh6
13.+ - (#4) Rh7
14.+ - (#4) Rh8
15.+ - (#5) g4
16.+ - (#5) Rh2+
17.+ - (#6) Rfg1+
18.+ - (#5) Rf2+
19.+ - (#10) Rh3
20.+ - (#11) Rf3

_Several_ of these moves take castling into accout.

After Rf4 Kxg3 my TB's show 28 moves.  The first move is 1. + - (#2) O-O, the
last is 28. + - (#15) Rh8.

I am 100% sure TB's do indeed take castling into consideration.
