It is possible to enter moves without the wonderful (you misspelled the word)
hint system. You turn it off in the "Options" menu under "Engines", where there
is a checkbox for "Heumas", the heuristic move assistant (isn't this also
available in CB light?). You can also keep it on and set the ply level higher to
improve the quality of the suggestions.

Personally I couldn't live without Heumas. I just tried an experiment and
entered the moves 1.e4 e5 2.Nf3 Nc6 3.Bb5 a6 4.Ba4 Nf6 5.0-0 Nxe4 6.Re1 Nf6
7.Bxc6 dxc6 8.Nxe5 Be7 9.d4 0-0 10.c4 Re8 11.Nc3 c5 12.d5 Bd6 13.Bf4 Bg4 14.Nxg4
Rxe1+ 15.Qxe1 Nxg4 16.Bg3 Qd7 17.Qd2 with exactly 33 clicks, i.e. one per ply.
Only on move 13 when I click g4 Heumas wants to move the knight there. I have to
use the right mouse key to correct it (that cycles through other possibilities),
so actually it is 34 clicks. I have watched Anand enter moves with perfectly
optimised clicks at blinding speed. He actually knows when Heumas is not going
to get it right and drags the piece prophylactically.

BTW you do know the keyboard input of Fritz? The program tries to interpret key
presses and executes a move as soon as enough information is available to make
it unambiguous. The principle is to type in the piece (including “p” for pawn)
and the destination square, possibly with a capture sign. The order is not
critical, so you can type 'nf3', 'f3n', '3nf' etc. For the bishop you have to
use l ("Läufer" in German), because b is required for the square co-ordinates.

Most often the move is executed after two or even one keypress. For instance in
the initial position 'nf' will move the knight from g1 to f3, since that is the
only knight that can move to the f-file. If you have only one legal move with
your king, typing 'k' is sufficient.

Here is a full example of entering the white moves in the sequence 1.e4 e5 2.Nf3
Nc6 3.Bb5 a6 4.Bxc6 dxc6 5.d4 exd4 6.Qxd4 Qxd4 7.Nxd4 Nf6 8.0-0

1.e2-e4   : pe4, ep4, e4, 4e

2.Nf3     : nf, fn (since only the knight can move there)

3.Bf1-b5  : lb, b5, l5 (only the bishop can move to the 5th rank)*

4.Bxc6    : lxc, lxn, lc6, c6 (only the bishop can move there)*

5. d4     : Pd4, d4p, 4pd, 4dp

6.Qxd4    : qx, q4, d4q, etc.

7.Nxd4    : nd4, nx (“knight takes”)

8.0-0     : kg, g1k, gk (“king to g-file”)

Try it out, it is at least great fun.
